| 摘 要： |
膨胀土掺石灰后其性质有很多改变。通过对荆宜高速公路膨胀土的石灰改性试验，得到了膨胀土加石灰后的工程性质的变化规律，如自由膨胀率、膨胀量、收缩率、塑性指数下降、抗剪强度与CBR增加等。从而为改善膨胀土的工程性质以满足工程设计的要求提供了可靠的试验数据。

| Abstract: | The properties of expansive soil have many changes after it is mixed with lime. This paper is based on the testing data of the lime mixed expansive soil from the expressway of Yichang-Jingmen. The changes in the engineering properties of expansive soil mixed with lime are obtained. It decreases the free swelling ratio, swelling capacity, shrinkage ratio and plastic index. It increases the shear strength and CBR. The research result can provide accurate testing data for improving the engineering properties of expansive soil in order to satisfying the requirements of the expressway engineering design. |
